Re: tabs not being displayed properly in Tiki4
I've confirmed the bug in the Strasa theme as well on one of our sites running Tiki 4.
I know for a fact that TABS plugin works great in Tiki 5 since I've been using it a lot for some of the new sites that we've been working on.
I'm sure the problem can be fixed for the next release of 4 but I don't know when that next patch is due. On the other hand Tiki 5 official release is very soon. If you are able to upgrade your site to Tiki 5 you would get the TABS plugin working correctly and also benefit from many of the new improvements.
Hope this helps,
Pascal
